granted. who churns their profile?. creation is enough info to pull just users created later than the last time your cache was updated. hooking last_modified, when/if it exists, would be nice. Thanks.

How about adding a way to query "last modified" on lists? For example, in Stack2Blog (stackapps.com/questions/611/…), we need to grab a user's entire list of answers. If we want to implement caching, it would be helpful to query whether or not the list of answers has changed (I assume this applies in other places as well).

@Edan Maor - that can be accomplished by sorting by creation (for new answers, or activity for new and changed answers), and setting min to the last query time. Variations on that approach allow for caching in a number of use cases.

Thanks, I didn't know that. I'll have a look at that now.
